When a guided projectile is fired, the high pressure generated by the gunpowder gas in the chamber produces a high impact accelerationtion of tens of thousands of g in the projectile, which makes the components of the projectile withstand a huge instantaneous, high-energy, strong impact load. This type of load environment results in the deformation and failure of the internal mechanical components and damage to all type of electronic components, leading to the failure of the entire guidance system. Selecting the correct cushioning material to store or dissipate the impact energy so that the peak value of the impact is reduced to within the range of the component is an effective technical approach. In this study, a mechanical analysis of the high-impact environment inside a certain type of artillery was conducted, the axial impact load variation curve of the projectile was drawn, and a buffer isolation mathematical model of the buffer material was established. This study obtains a visualization interface using Python to solve the problem intelligently. By changing the mass of the mass block, the equivalent stiffness and equivalent damping value of the buffer material in the program script, researchers can use the model to draw the displacement, velocity and acceleration curves of the two mass blocks simultaneously, and obtain the buffering efficiency and maximum elastic compression of the buffer material. When the equivalent damping is the same, this study obtains the buffering efficiency curve and the maximum elastic compression curve changing with the stiffness through the model. The results show that in the range of elastic deformation, the buffering efficiency is proportional to the length of the buffering material but inversely proportional to its equivalent stiffness. The mathematical model provides technical support for the pre-design development and selection of cushioning materials in high-impact environments.
